Physical Theories, Eternal Inflation, and Quantum Universe <https://arxiv.org/abs/1104.2324>, Yasunori Nomura
We conclude that the eternally inflating multiverse and many worlds in quantum mechanics are the same. Other important implications include: global spacetime can be viewed as a derived concept; the multiverse is a transient phenomenon during the world relaxing into a supersymmetric Minkowski state. We also present a theory of “initial conditions” for the multiverse. By extrapolating our framework to the extreme, we arrive at a picture that the entire multiverse is a fluctuation in the stationary, fractal “mega-multiverse,” in which an infinite sequence of multiverse productions occurs. "Therefore, we conclude that the multiverse is the same as (or a specific manifestation of ) many worlds in quantum mechanics." "In eternal inflation, however, one first picks a causal patch; then one looks for observers in it.” Our framework does not follow this approach. We instead pick an observer first, and then construct the relevant spacetime regions associated with it. Instead of admitting the existence of the “beginning,” we may require that the quantum observer principle is respected for the whole history of spacetime. In this case, the beginning of our multiverse is a fluctuation of a larger structure, whose beginning is also a fluctuation of an even larger structure, and this series goes on forever. This leads to the picture that our multiverse arises as a fluctuation in a huge, stationary “megamultiverse,” which has a fractal structure." The Multiverse Interpretation of Quantum Mechanics <https://arxiv.org/abs/1105.3796>, Raphael Bousso and Leonard Susskind In both the many-worlds interpretation of quantum mechanics and the multiverse of eternal inflation the world is viewed as an unbounded collection of parallel universes. A view that has been expressed in the past by both of us is that there is no need to add an additional layer of parallelism to the multiverse in order to interpret quantum mechanics. To put it succinctly, the many-worlds and the multiverse are the same thing [1]. Jason -- You received this message because you are subscribed to the Google Groups "Everything List" group.
